Abstract

The invention relates to the field of plastic material processing, and particularly relates to a pretreatment method and application of an acrylate assistant cross-linking agent, a graft polymer of the acrylate assistant cross-linking agent and a preparation method of the graft polymer. The pretreatment method of the acrylate assistant cross-linking agent comprises the following steps: taking liquid peroxide or a peroxide solution, and spraying or / and dipping the liquid peroxide or the peroxide solution on the acrylate assistant cross-linking agent, so as to obtain a pretreated acrylate assistant cross-linking agent. The pretreatment method has the advantages that the mechanical property of a plastic product can be improved, the processability of the plastic product is improved, and the preparation method is simple.

Description

technical field [0001] The application relates to the field of plastic material processing, more specifically, it relates to a pretreatment method and application of an acrylate auxiliary crosslinking agent, a graft copolymer of an acrylate auxiliary crosslinking agent and a preparation method thereof. Background technique [0002] When processing plastic products, in order to improve the mechanical properties of plastic products, a certain proportion of reinforcing materials, such as fibers and inorganic fillers, are usually added to the system. For example, the patent application document with the application publication number CN109705451A discloses a method for preparing a fiber-reinforced polypropylene strength composite material, which uses a high proportion of glass fiber and boron fiber to improve the mechanical properties of the polypropylene material. The patent application document with the application publication number CN109294067A discloses a glass fiber reinfo...

Problems solved by technology

[0003] Although the method of adding glass fibers or inorganic fillers can improve the mechanical properties of plastics such as strength and hardness, there are two disadvantages in this reinforcement method: First, due to the large proportion of glass fibers and inorganic fillers, the density of the product will be reduced. increase, which weakens the advantages of light weight of plastic products

The second is the problem of low interfacial compatibility between glass fiber and polypropylene and other polymer materials. When the amount of inorganic filler increases, there is also the problem of poor compatibility with the polymer, which leads to the flow of the polymer when it melts. In order to improve this problem, it is necessary to modify the glass fiber to improve the interface compatibility between the glass fiber and polypropylene, or to treat the surface of the inorganic filler with a silane coupling agent , to improve the compatibility of inorganic fillers and polymer materials, but this makes the production process more complicated and increases the production cost

[0004] Therefore, there are certain defects in the method for plastic reinforcement at present.
